A380 is grounded by Quantus due to one uncontained engine failure so why was the B777 fleet allowed to continue to fly (ETOPS et all) after the BA B777 dual engine failure resulting in a complete power loss?
Only Quantas and Singapore Air are grounding their fleets voluntarily. The rest of the A380s are not grounded. The 777 fail was different also because it wasn't a brand spankin new airplane. However, in both cases (today and the 777) RR seems to struggle with controls design.
